Abstract
Crystals of the title salt, C21H20OP+·NO3−, are composed of acetonyltriphenylphosphonium cations and nitrate anions that mainly interact through electrostatic forces. The P atom in the cation has a slightly distorted tetrahedral environment, with C—P—C angles ranging from 104.79 (7) to 112.59 (6)°. The sum of O—N—O angles of the nitrate anion is 359.99°, reflecting its trigonal–planar character. C—H⋯O hydrogen bonds help to consolidate the crystal packing.
